2018-02-26 11:16:05 -03:00
Roberto Ierusalimschy 9243c414d9 first version of empty entries in tables

2018-02-23 10:16:18 -03:00
Roberto Ierusalimschy c72ac048b9 conditional jumps "deunified"

2018-02-09 13:16:06 -02:00
Roberto Ierusalimschy 318a9a5859 new opcode 'PREPVARARG'

Roberto Ierusalimschy d2fb34ac88 'OP_TAILCALL' calling C functions finishes the call and returns
(instead of waiting for following 'OP_RETURN')
2018-01-14 15:27:50 -02:00

2017-12-22 12:16:46 -02:00
Roberto Ierusalimschy 1d5b885437 when running Lua code, there is no need to keep 'L->top' "correct";
set it only when needed.
2017-12-20 12:58:05 -02:00
Roberto Ierusalimschy 3153a41e33 no need to save 'pc' in case of allocation errors
(allocation errors do not call message handlers)
2017-12-19 14:18:04 -02:00
Roberto Ierusalimschy d388c165ef new opcodes 'FORLOOP1'/'FORPREP1' for "basic for" (integer variable
with increment of 1)
2017-12-18 15:53:50 -02:00
Roberto Ierusalimschy 86431a2f1c new opcodes BANDK/BORK/BXORK. (They do not use immediate operands
because, too often, masks in bitwise operations are integers larger
than one byte.)
2017-12-13 16:32:09 -02:00
Roberto Ierusalimschy c7ee7fe026 new opcodes OP_SHLI/OP_SHRI 2017-12-04 15:41:30 -02:00

Roberto Ierusalimschy 196c87c9ce no more 'stackless' implementation; 'luaV_execute' calls itself
recursively to execute function calls. 'unroll' continues all
executions suspended by an yield (through a long jump)
2017-11-23 14:41:16 -02:00
Roberto Ierusalimschy 3c230cc825 using 'A' for register instead of 'B' in relational opcodes
('R(A)' is already created by default for all instructions.)
2017-11-22 17:15:44 -02:00

Roberto Ierusalimschy 5440b42f43 using 'trap' to stop 'luaV_execute' when necessary (tracing and
to update its copy of 'base' when the stack is reallocated)
2017-11-13 13:36:52 -02:00
Roberto Ierusalimschy 32fef60743 detail ('Protect' defined as an expression) 2017-11-08 17:01:02 -02:00

Roberto Ierusalimschy 722bdbe17d no more 'getBMode'-'getCMode' (imprecise + we will need more space

2017-09-28 13:53:29 -03:00
Roberto Ierusalimschy 1b10033583 new function 'luaT_trybiniTM'
to handle tag methods for instructions with immediate integer arguments
2017-09-27 15:59:08 -03:00
Roberto Ierusalimschy 00e728af88 binary operators use R instead of RK
faster + nobody uses RK(B), so B can be smaller (freeing one bit
for more opcodes, soon)
2017-09-26 15:14:45 -03:00
Roberto Ierusalimschy abb17cf19b new opcode OP_LOADF (load immediate float) 2017-09-19 15:38:14 -03:00
Roberto Ierusalimschy 80d9b09f35 jumps do not close upvalues (to be faster and simpler);
explicit instruction to close upvalues; command 'break' not
handled like a 'goto' (to optimize removal of uneeded 'close'
instructions)
2017-09-13 16:50:08 -03:00

2017-05-13 10:54:47 -03:00
Roberto Ierusalimschy 5c8770f896 back to old-style vararg system (with vararg table collecting extra
arguments)
2017-05-13 10:04:33 -03:00
Roberto Ierusalimschy 7647d5d13d revamp of fast track for table access (table set uses the same
macros as table get + new macro for integer keys)
2017-05-11 15:57:46 -03:00
Roberto Ierusalimschy 7184f6343a more integer fast tracks (for OP_LT, OP_LE, OP_SETTABLE, and OP_GETTABLE) 2017-05-10 14:32:19 -03:00

Roberto Ierusalimschy e8757a73e6 'luaV_execute' keeps local copy of program counter and hook mask,
to avoid excessive access to globals.
2017-05-05 14:16:11 -03:00
Roberto Ierusalimschy 2376eb6347 barrier for prototype's cache (with new gray list 'protogray' to keep
prototypes to have their caches visited again) + constant 'MAXMISS'
2017-05-04 10:32:01 -03:00
Roberto Ierusalimschy 8634b2a011 added 'cachemiss' field to prototype to avoid wasting time checking

Roberto Ierusalimschy 173e41b2eb new opcode OP_ADDI (for immediate integer operand) (Experimental) 2017-04-26 14:46:52 -03:00
Roberto Ierusalimschy cb3d5dce30 opcodes 'OP_GETTABUP'/'OP_SETTABUP' operate only with string keys,
so they can use fast-track table access
2017-04-24 17:26:39 -03:00
Roberto Ierusalimschy 6a98aa0bb0 new opcode LOADI (for loading immediate integers) 2017-04-20 16:53:55 -03:00
Roberto Ierusalimschy a3d36fe283 Upvalues collected like everything else (with mark-sweep) instead
of reference count (simpler and better for generational mode)
2017-04-11 15:41:09 -03:00
Roberto Ierusalimschy 2331e1beec small changes in 'luaC_upvalbarrier' 2017-04-06 10:08:56 -03:00
Roberto Ierusalimschy fd51651684 new macro 'vmfetch' to help changing code to computed goto's (macro
abstracts the code to run before each instruction)
2016-02-05 17:59:14 -02:00
Roberto Ierusalimschy 1a44e82200 'luaV_fastget' only treats the real fast case (table with a non-nil

2016-01-05 14:07:21 -02:00
Roberto Ierusalimschy a272fa66f0 bug: Metatable may access its own dealocated field when

Roberto Ierusalimschy 9a5d6aedb7 trying to optimize a little 'luaD_poscall' 2015-11-13 11:24:26 -02:00
Roberto Ierusalimschy 04587b6256 macro with empty argument can be seen as macro with no argument; better
to avoid that
2015-11-12 16:08:58 -02:00
Roberto Ierusalimschy ff1289a361 in 'luaD_call', use two functions instead of one with fixed boolean
argument
2015-11-02 16:48:07 -02:00
Roberto Ierusalimschy c5363a1b58 in 'luaD_precall', in vararg functions, complete missing parameters
only after moving them to final place (avoids checking the stack
again)
2015-11-02 12:06:01 -02:00
Roberto Ierusalimschy 07a2dcacbf flag CIST_REENTRY changed to CIST_FRESH (its negation); fresh invocations
seem to be less frequent than reentries. (So, avoid setting flag on
the frequent case.)
2015-11-02 09:43:17 -02:00
Roberto Ierusalimschy 257961c601 OP_SELF can use 'luaV_fastget' specialized for strings, as it
is applied only to string keys
2015-10-28 12:50:09 -02:00
Roberto Ierusalimschy 8004ab756f hook test in 'luaV_execute' reduced to minimum (rest done in
'luaG_traceexec'; no difference in performance for the non-hook
case, but keeps 'luaV_execute' a little simpler) + 'base' updates
replaced by 'Protect' (which serves this rule)
2015-10-22 12:40:47 -02:00
Roberto Ierusalimschy f7670781cf cleaner definition for 'luaC_condGC', using 'pre'/'pos' parameters 2015-10-20 15:56:21 -02:00
Roberto Ierusalimschy df8b996bcc 'Protect' in table operations is not needed in the fast track
+ removal of a few dead macros
2015-10-20 15:41:35 -02:00
Roberto Ierusalimschy ee5edb6b68 macros 'getaddrstr' and 'getstr' unified (they do the same thing) 2015-09-17 12:51:05 -03:00
Roberto Ierusalimschy b91bc93fd3 'setobj2t' incorporated into 'luaV_fastset' + 'invalidateTMcache'
is not needed in the fast track (as it does not create new
entries)
2015-09-09 10:44:07 -03:00
